New to Hifi

Hello friendly enthusiasts,

I have built a Purifi 1ET6525 based stereo power amp, and bought myself a pair of KEF R3 Metas.

Now I need a signal to feed it, that will be good enough to get the most from my system.

Does anyone here know the Hypex preamp/dac/streamer modules? How good is it actually? If price is anything to go by (1995 eur), it should be pretty excellent and fully up to the task, but I know that’s not always the case. What would I be paying for the same quality as a finished consumer product? Are there better alternatives?

Thank you!
